occipital lobe
Brain's sight center
The occipital lobe is the region at the back of the brain primarily responsible for processing visual information.
Damage to this area can cause blindness or visual disturbances even when the eyes function normally.
The tumor was located in her occipital lobe, affecting her peripheral vision.
